I know this is 2 years old now, but I am having the same issue with my 2018 Fusion Hybrid, and I wondered if anyone ever found a solution for this? The thing is, when I first got my Fusion, I am 100% certain that the Vehicle->Lock menu contained functions to disable AutoLock and AutoUnlock. I scrolled through the ENTIRE Setup menu the day I brought it home, and they were there. After a week or so, and reading in the Owner's Manual about all the setup options, I went to the car to turn off AutoLock, and that menu item was GONE!!! (although AutoUNLock is still there) So... it's not some initial setting of the car. As for JayFusion's comment about some cars on the lot having that setting and some not - is it possible that the cars without that option have more miles on them, and maybe that option only appears for the first X miles, then disappears? Is something like that even possible? I'm still trying to figure out how to disable AutoLock on my vehicle......

I just found this thread. I have a 2018 Fusion Hybrid SE, and I had the same problem the first few months I owned it. Frequently after unlocking the doors with the keypad, I would get into the car and then find the trunk had opened. I assumed I was hitting the 6 key somehow after entering my code and tried to be more careful (my code ends with 4). After a few months, the trunk seemed to stop opening by itself. My suspicion was always that after I entered the code and actually opened the door, my finger somehow landed on the 6 key while entering the car (or while opening the door), but I was never able to prove this. I can say that I have not had the trunk open while unlocking for probably 4 or 5 months now, so maybe whatever the bug is, it goes away after some time?
